Dates in Chinese: Years, Months, Weekdays, and Birthdays

By Ray Banks·September 15, 2026·Vocabulary

Chinese dates always run from largest unit to smallest: year → month → day, as in 2026年9月15日 — spoken 二〇二六年九月十五号/號 (èr líng èr liù nián jiǔ yuè shíwǔ hào), "September 15, 2026." That one ordering rule, plus the numbers 1–12, gets you the entire system: months are just numbers, weekdays are just numbers, and there are no month names or weekday names to memorize. This guide covers the day/date format, all twelve months, the three parallel weekday systems (and who uses which), how to read years digit by digit, birthdays, and where dates sit in a sentence.

How do you say the date in Chinese?

Month + 月 (yuè), then day + 号/號 (hào) in speech or 日 (rì) in writing. September 15 is 九月十五号 (jiǔ yuè shíwǔ hào) out loud, and 9月15日 on a poster, a ticket, or a form. 号/號 behaves like a measure word for calendar days — the same slot logic covered in our guide to Chinese measure words — while 日 is the character you'll read everywhere print wants to be formal.

To ask, swap the number for 几/幾 (jǐ, "which/how many"): 今天几号?/今天幾號? "What's the date today?" Dates like this can even drop 是 in casual speech — 今天九月十五号 is a complete, correct sentence.

How do months work in Chinese?

Number + 月. That's the whole system — January is "one-month," December is "twelve-month." The characters are identical in simplified and traditional. If numbers above ten are still shaky, review Chinese numbers 1–100 first; the months come free afterward.

One trap: 一月 is the month of January; 一个月/一個月 (yí ge yuè) with the measure word is a duration, "one month." Miss the 个/個 and "I studied for a month" turns into "I studied in January."

What are the three ways to say weekdays?

Mandarin has three parallel weekday systems, all built the same way: a "week" word plus the numbers 1–6 for Monday through Saturday, with Sunday taking 天 (tiān) or 日 (rì) instead of a number. They're fully interchangeable in meaning — the choice is register and region.

Regional texture, since neither side of the strait owns "correct Chinese": on the Mainland, 星期 is the neutral default and 周 is extremely common, especially in writing and compounds like 周末 (zhōumò, weekend). In Taiwan, 星期 and the more colloquial 禮拜 dominate speech, the traditional script writes the week word as 週 (週末, 週五), and 期 is read second tone — Taiwanese speakers say xīngqí where Mainland speakers say xīngqī. Both readings are standard in their region. For pronunciation drills and memory hooks on all seven days, see days of the week in Chinese.

How do you say years in Chinese?

Digit by digit, then 年 (nián). 1998 is 一九九八年 (yī jiǔ jiǔ bā nián) — never "one thousand nine hundred ninety-eight." 2026 is 二〇二六年 (èr líng èr liù nián); the zero can be written 〇 or 零. To ask, use 哪一年 (nǎ yī nián, "which year") or 几几年/幾幾年 (jǐ jǐ nián) casually for two-digit answers.

One thing that surprises visitors to Taiwan: official documents there often use the Republic of China calendar, 民国/民國 (Mínguó), which counts from 1912 — so 2026 appears as 民國115年. Subtract 1911 from the Western year and you can read any Taiwanese form or ID date. Everyday conversation in Taiwan still uses Western years; 民國 years are a reading skill more than a speaking one.

How do you talk about birthdays?

The word is 生日 (shēngrì), and the question and answer reuse everything above:

The greeting is 生日快乐/生日快樂 (shēngrì kuàilè, "happy birthday"), and for the year of birth use the 出生 pattern from the previous section. Birthday dinners are where learners first deploy all of this at once — usually surrounded by 家人 (jiāren, family), so it pairs naturally with our Chinese family vocabulary guide when the invitation includes grandparents, aunts, and cousins whose titles you'll be expected to know.

Where do dates go in a Chinese sentence?

Two rules cover almost everything. First, time expressions come before the verb (or before the subject, for emphasis) — never dangling at the end the way English allows. Second, there is no word for "on" or "in": the date sits in the sentence bare.

When a full date and weekday appear together, the biggest-to-smallest rule keeps going right through the weekday: 2026年9月15日星期二 — "Tuesday, September 15, 2026," with the elements exactly reversed from English. And like calendar dates, weekdays can be predicates with no verb at all: 今天星期二 (Jīntiān xīngqī'èr), "Today is Tuesday."

How common are date words in real Chinese text?

Very — which is why dates repay early study. Measured across the 658 graded stories in the Literate Chinese catalog (July 2026), ten date-and-time characters rank inside the 150 most frequent characters of the whole corpus:

In other words, you cannot read even beginner Chinese without meeting dates constantly — and the reverse is also true: a few weeks of graded reading will drill this entire article for free. Dates are one slice of a larger system of time words (今天, 昨天, 上个月/上個月, 去年) that we map in Chinese time vocabulary; once both are in place, the fastest way to make the patterns automatic is to meet them in context — try reading your first story and count how many dates you spot.
